Reading saved WiFi Connection Details

[swiftie]

I've offered to help a complete stranger with a problem in their laptop's WiFi. To test the system, I'll end up attempting to connect their laptop to my WiFi.

I'm not concerned about this; I have no reason to be suspicious of the other person, we met via a local recycling website. They live just round the corner from me, so if my system gets compromised, I can lob a brick through their window...

However, their Windows system (unknown version at this point) will cache my WiFi connection details, including my password. Do I have to worry about my password being extracted from the saved configuration details?

I'm not concerned about CIA/Government/SciFi levels of hacking, as long as extracting the password isn't something really simple (and I'm not fishing for hints on how to extract the password)

Once you have completed your testing...
...remove your network (SSID) from the stranger's laptop:

Doing that will tell Windows to forget the key (password).
I don't know of a way or tool to extract the key of a forgotten network.

And/or, change the Wireless Access Point key on your network.
